Explore our premium grade functional ingredients optimized for global distribution, sports nutrition, and clean label products.
The global protein powder market is undergoing a structural transformation. Driven by systemic lifestyle changes, vegan expansion, and metabolic wellness awareness, standard commodities are being replaced by bio-functional, highly soluble, and customizable matrixes. Brands no longer require simple bulk exports; they demand clinical integration, clean-label compliance, and precise particle engineering.
From plant proteins like isolated soy and yeast proteins to high-density amino acids and marine peptides, factories must adapt processing frameworks to ensure low-allergen profiles, neutral organoleptic properties, and rapid dispersion indices. Hangzhou Soy Extracts Co., Ltd. stands at this intersection, providing global logistics routing and customizable B2B formulation models.
Hangzhou Soy Extracts Co., Ltd. is a leading China dietary supplement ingredients manufacturer specializing in the research, development, production, and supply of high-quality nutraceutical raw materials.
Supported by a highly experienced research and development team, we continuously explore new ingredient technologies and formulation solutions to meet the evolving needs of the global nutraceutical market.
Quality control is integrated into every stage of production. From raw material sourcing and manufacturing to final inspection and packaging, strict QA/QC procedures ensure consistency, safety, and purity.
By leveraging advanced technologies, stable supply chains, and professional technical support, we have established long-term B2B partnerships with brands in over 50 countries.
Leveraging advanced production technologies and modern manufacturing facilities, we offer an extensive portfolio of dietary supplement ingredients, including botanical extracts, plant proteins, amino acids, vitamins, minerals, functional ingredients, and other nutraceutical raw materials. These ingredients are widely used in dietary supplements, functional foods, sports nutrition products, health beverages, immune support formulations, and wellness applications.
How we scale your custom protein powder formulas from lab pilot tests to multi-ton container shipments.
Custom amino acid ratios, flavoring, sweetness profiling, and active ingredient blending based on your market criteria.
Testing solubility, sensory parameters, and stability under different temperature and humidity thresholds.
Validation of incoming proteins (Soy, Yeast, Fish Collagen) using chromatography and mass spectrometry.
Standardized automated packaging lines utilizing pouches, tubs, and bulk bags under high-grade GMP conditions.
Providing custom declarations, health certificates, Certificate of Analysis (COA), and secure sea/air shipping.
Using natural proteolytic catalysts like papain enzyme, our manufacturing plant selectively breaks down complex protein chains into digestible peptides. This reduces viscosity in high-protein beverages and speeds up biological absorption.
| Parameter | Standard SPI | Enzymatic SPI |
|---|---|---|
| Average Mol. Weight | >100 kDa | <5,000 Da |
| Dispersion Time | >90 seconds | <15 seconds |
| Viscosity (10% Sol) | High gel-forming | Free-flowing liquid |
Our technology team focuses on optimizing plant proteins (such as soy isolates and yeast proteins) to match the essential amino acid profiles typically found in whey. By blending precise ratios of plant isolates with isolated amino acids (like L-Valine), we produce a complete plant-based protein with a high Digestible Indispensable Amino Acid Score (DIAAS).
In addition to plant matrices, we use specialized extraction technology to manufacture marine products like fish collagen peptide powders. Our process maintains structural purity while keeping the finished powders completely water-soluble and stable in acidic formulas.
A look inside Hangzhou Soy Extracts Co., Ltd.'s processing facilities, laboratory testing systems, and production lines.
Exporting health ingredients requires absolute compliance with food safety regulations. Hangzhou Soy Extracts Co., Ltd. maintains a complete quality system to ensure every shipment complies with local regulations in destination markets.
All our plants operate under ISO9001, ISO22000, Kosher, and Halal standards. Select raw materials are also FDA-registered or USDA Organic certified.
Every production run is tested for heavy metals (Lead, Arsenic, Cadmium, Mercury) and microbiological activity (Salmonella, E. Coli, Yeast & Mold).
We supply Certificate of Analysis (COA), Allergen Declarations, Non-GMO Statements, and Safety Data Sheets (SDS) to ensure smooth customs clearance.
We offer specialized export pathways to accommodate the logistical requirements of major regional hubs:
*Note: Custom logistics arrangements, including ex-work (EXW), FOB, CIF, or DDP delivery profiles, can be structured through our logistics office.
How our bulk raw materials are incorporated into commercial consumer goods, medical dietary nutrition, and animal feed.
High-purity amino acids (like L-Valine) and soy isolate proteins are used in muscle building powders, meal replacement shakes, and functional snacks like creatine gummies to support recovery.
Formulas designed to support joint health, skin structure, and cell energy. Key active ingredients like CoQ10 (99%), fish collagen peptides, and antioxidants are blended into easy-to-use capsules or powder supplements.
Proteins and processing acids (like fumaric acid) are used as high-grade animal nutrition ingredients (such as corn gluten meal and aquatic feed additives) to support healthy growth patterns.
Get immediate clarity on manufacturing lead times, minimum order quantities (MOQs), quality testing protocols, and custom formulation options.
For custom formulation OEM/ODM protein powders, the standard MOQ starts at 1,000 kg (1 metric ton) per flavor profile. For raw bulk ingredients like Soy Protein Isolate or Fish Collagen Peptide Powder, we can support smaller trial runs starting at 500 kg, depending on packaging requirements.
We operate dedicated production lines for plant-based soy protein and marine-based fish collagen. All lines are cleaned using validated CIP (Clean-in-Place) protocols between production runs. Standard allergen sweep reports and ELISA testing validations are performed to prevent cross-contamination.
We offer accelerated and real-time stability testing for custom powder blends. Products are stored in climate chambers to monitor active ingredient decay, moisture uptake, and microbiological stability under varying conditions. This allows us to offer 24-month shelf-life verification for most powder formulations.
Yes. Our processing plant uses air-classifying mills to customize particle size profiles from 80 mesh up to 200 mesh. A smaller particle size of 200 mesh is recommended for ready-to-mix instant protein shakes to improve mouthfeel, while a larger particle size is ideal for tablet compression or capsule filling.
Every exported batch is accompanied by a Certificate of Analysis (COA) detailing physical parameters, moisture levels, active assay percentages, heavy metals, and microbiological assay statistics. We also provide BSE/TSE-free certificates, non-GMO statements, and certificate of origin documents as requested.
Yes, our application lab provides custom flavor development and masking solutions for plant-based proteins. We offer natural and artificial options (such as vanilla, chocolate, fruit, and berry profiles) and can formulate using natural sweeteners like stevia, monk fruit, or erythritol to meet clean-label demands.
